Data and scripts describing dissolved organic matter character across a stream network in Oregon following the 2020 Holiday Farm Wildfire

In 2020, the Holiday Farm Wildfire burned ~18 % of the McKenzie sub-basin in Oregon, USA. To investigate the impact of the wildfire on in-stream dissolved organic matter character, we collected water samples from 129 stream sites within the McKenzie sub-basin stream network over four distinct seasonal wetness conditions (wetting, wet, drying, dry) between November 2022 and May 2024. Absorbance and excitation emission matrices were collected for each sample in addition to dissolved organic carbon. This data was used to develop a PARAFAC model, which was used to create spatial network models to model the relative percentages of each PARAFAC component across the stream network. This data package consists of (1) a spreadsheet spreadsheet containing DOC concentrations, relative percentage of each PARAFAC component, landscape characteristics, and site information for the stream sites within the McKenzie sub-basin, OR, USA. (2) A spatial stream network (SSN) object developed for the McKenzie sub-basin from the proceeding data. (3) Scripts written in R used to process, analyze, and report our findings from this data.
